Class C – Electrical Equipment such as appliances, circuit breakers, , outlets, and wiring. Do not use water to extinguisher electrical fires

Class D - Combustible Metals such as potassium, sodium, magnesium, titanium, and other combustible metals. Commonly used in laboratories

Class K - Cooking Oils and Animal Fat used in cooking. Required in any commercial kitchen that uses these products to cook.

ABC Type - A multi-purpose dry chemical fire extinguisher. Contains a powder. This is the most common type of fire extinguisher. Located in all types of buildings throughout the world, it is used where the type of fire that may occur involves A, B, and C types of fires. These are as follows:

Class B fires involve flammable or combustible liquids. Petroleum, grease and oil fires are included in this class.

Class C fires involve Electrical Equipment such as appliances, circuit breakers, , outlets, and wiring. Do not use water to extinguish electrical fires.

BC Type - used mostly in industrial settings where fires involving organic solid such as paper or not as common. Used where B and C types of fires are may occur. These are as follows:

Class B fires involve flammable or combustible liquids. Petroleum, grease and oil fires are included in this class.

Class C fires involve Electrical Equipment such as appliances, circuit breakers, , outlets, and wiring. Do not use water to extinguish electrical fires.

K-Class Type - used in restaurants, churches, daycares, schools, or any location where a kitchen is located. Must be located within 30 feet of the appliance where grease fires may occur. If the kitchen has a fryer then it is mandatory that the a K-Class fire extinguisher be in place. Even if the kitchen does not have a fryer, it is mandatory to have a K-Class fire extinguisher in place if it is likely that grease or oils will be used to cook at any time. These are as follows:

Class K fires involve cooking fat, grease, or cooking oil.

D Type - used where fires involving combustionable metal may occur. Locations such as labs, factories, mining operations, and metal foundries are required to have these type of fire extinguishers in place for use. These include:

Class D fires involve combustible metals

CO2 Type - A gas agent fire extinguisher where the gas displaces oxygen and removes heat from the combustion zone or inhibits chemical chain reaction. They are labeled clean agents because they do not leave any residue after discharge. These type are ideal for sensitive electronics and documents. Includes the following:

CO2 - Used with sensitive documents and electronics.

Halogen Type - Halon (including Halon 1211 and Halon 1301), a gaseous agent that inhibits the chemical reaction of the fire. Classes B:C for lower weight fire extinguishers (2.3 kg; under 9 lbs) and A:B:C for heavier weights (4.1–7.7 kg; 9–17 lbs). Banned from new production, except for military use, as of January 1, 1994 as its properties reportedly contribute to ozone depletion. Halon 1301 and 1211 are being replaced with new halocarbon agents and should be switched to new types of fire extinguishers. Currently Halotron I, Halotron II, FE-36 Cleanguard and FM-200 are replacements that may be used. Includes the following:

FE 36 Cleanguard- Clean, used for sensitive electronics and documents, and computer rooms..

Halotron i - Clean, used for sensitive electronics and documents and computer rooms.

Halotron II - Clean, used for sensitive electronics and documents and computer rooms.

FM 200 - Usually large tanks connected used used for sensitive electronics and documents, computer rooms and sometimes where explosions may occur..

Water Type - Cools burning material by absorbing heat from burning material. Effective on Class A fires, Water fire extinguishers 2.5 gallons (9 liters) of water in a tall, stainless steel cylinder. Water Mist uses a fine misting nozzle to break up a stream of deionized water.

.

Water - APW - Air Pressurized water used for Class A fires involve organic solids such as paper and wood

Water Mist - Class A and C fires.

The guidelines above are not meant to be all inclusive or for do it yourself fire extinguisher work. These guideline are for general knowledge only. Always consult and use a professional fire protection company and your local Fire Marshal before installing any particular type of fire extinguisher.

Warning!! The use of ABC or Halon type fire extinguishers around swimming pools, spas or other areas
